Use the following formulas to answer the questions below: t(m, r) = r + o.6(m — r) 220 - x where r = resting heart rate: m = maximum healt rate, and x = age recall our discussion of heart rate and composition of åmctions from the end of the section. find the training heart rate fianction: t (m) for a person with a resting healt rate of 72 beats per minute: then find the following. a. find the maximum heart rate function: m(x) for a person x years of age.

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
